DM74S257N規(guī)格書詳情

General Description

These Schottky-clamped high-performance multiplexers feature 3-STATE outputs that can interface directly with data lines of bus-organized systems. With all but one of the common outputs disabled (at a high impedance state), the low impedance of the single enabled output will drive the bus line to a HIGH or LOW logic level. To minimize the possibility that two outputs will attempt to take a common bus to opposite logic levels, the output enable circuitry is designed such that the output disable times are shorter than the output enable times.

Features

■ 3-STATE versions S157, S158, with same pin-outs

■ Schottky-clamped for significant improvement in A-C performance

■ Provides bus interface from multiple sources in high-performance systems

■ Average propagation delay from data input 4.8 ns

■ Typical power dissipation 320 mW
